Hello to the Triumph list!
I'm new on the list and am a little overwhelmed by the volume of
messages!
With reference to the SAAB/Triumph connection, not only does the TR7
share components with the SAAB motor but when rebuilding my STAG motor,
many of the timing components and bearings were actually in SAAB boxes!
>From what I understand, the first thing that SAAB did after Triumph
designed the motor for them was to change the head studs so that they did
not enter the block on an angle, and by doing so eliminated the problem
that most Stags and many TR7s had of blowing head gaskets.
